“…Hydrolysis and oxidation are consequences of poor oil conservation. Acid number measures the amount of free fatty acids resulting from hydrolytic reactions of triglycerides, making it a quality criterion to report conservation status of an oil (Kpegba et al, 2017). Kandji et al (2001) found an acid number of 2.60 for S. indicum L oil that are close to our values for S. radiatum.…”

Several species of sesame have been extensively studied but little is known about Sesamum radiatum (SR). In this work, seeds roasting impact on two Sesamum spp, SR and S. indicum (SI) oils quality was studied. Physicochemical parameters (PP), fatty acids profile (FAL) and antioxidant activities were evaluated using spectrophotometry methods and gas chromatography coupled to mass spectrometry (GC-MS). Unroasted seeds (US) of SR oil extraction showed a yield of 40.26 ± 0.86% while roasted seeds (RS) at different temperatures (145-200°C) demonstrated a yield of 40.11 ± 1.36%. Evaluation of PP of oils according to the French Standardization Association (AFNOR) standards showed the following results: refractive index: 1.47435-1.47665 for SR and 1.46660-1.47065 for SI; acid number: 2.01-3.35 for RS against 10.04±0.53 mg KOH/g for US; saponification number: 186.82-191.53 for SR and 189.74-190.42 mg KOH/g for SI. Iodine value: 100.31-127.74 for SR against 117.96-128.04 g I2/100 g for SI; peroxide value: 1.19-4.00 for SR against 1.66-2.58 meq/Kg active O2 for SI. FAL was slightly modified during roasting showing that SR oil is an oleic-linoleic oil. More, SR oil demonstrated twice antioxidant activity than SI. These results demonstrated that roasting has positive effects on SR oil nutritional quality. SR oil could be recommended in food after toxicity studies.

“…It was a species traditionally known in the drier central and northern parts of countries such as Benin, Cameroon, Côte d'Ivoire, Ghana, Nigeria, Togo and Uganda. It was a species of African savannas and more precisely of West Africa where it is known as endemic [65][66][67]. The species was found more in Sudanese and Sudano-Sahelian climates with a rainfall of less than 1000 mm [56].…”

The impact of anthropogenic activities on the spatiotemporal dynamics of the forest of Dogo-Kétou has been studied in relation to climate change observed in southeastern Benin. Especially, this study has detected the changes in climate parameters in southeast Benin from 1954 to 2016 and in forestland use from 1986 to 2018. A climatic break was detected, and the annual and monthly rainfall and temperature averages, the rainfall indexes, the concentration of precipitation, the number of rainy days according to the World Meteorological Organization and the bioclimatic aridity indexes were assessed. A GIS analysis was also performed based on Landsat images from 1986, 2000 and 2018 to detect the dynamic of land use and land cover of the classified forest of Dogo-Kétou. Excel 2016, Rx64 4.1.2, Rclimdex301, Khronostat1.01 and ArcGIS were used. The rainfall series showed a break in 1969. The segment from 1954 to 1968 was a period of excess rainfall with an average of 1420.46 mm/year. The segment from 1969 to 2016 was a rainfall deficit period with a reduction of 12 to 37% of rainy days and an increase of dry days for 21.4 days/year. In this last segment, southeast Benin experienced trends of its climate towards a sub-arid and arid climate. The agglomerations and bare soil of the forest of Dogo-Kétou increased to an area almost double the size between 1986 and 2018. The tree and shrub savannas gained in space from 12.1% in 2000 to 38.9% in 2018 and the dense forest and wooded savannas regressed by 52.6% in 1986 to 36.1% in 2000 then to 4.3% of the forest area in 2018. The subequatorial climate of southeastern Benin is gradually evolving towards a dry climate. The dense forest in this area is also gradually disappearing, giving way to savannas. This transformation towards the savannas was due to anthropogenic actions whose effects were strongly accentuated by climate change in this part of Benin and West Africa.
